Abstract: Abstract of the Disclosure A thermally responsive valve device having non-linear flow characteristics.  The thermally responsive valve device includes movable and stationary valve structure.  A movable valve member is movable to adjust the open area of a flow passage, but movement of the movable valve member provides a non-linear relationship between the area of the flow passage created and the distance of travel of the movable valve member.     The movable and/or the stationary valve member is provided with an irregularly shaped portion so that with slight opening movement of the movable closure member less fluid flow than normal is permitted.  As the movable valve member continues to move in an opening direction, the fluid flow increases at a predetermined non-linear rate until a specific flow rate is achieved.  This operating characteristic eliminates or dramatically reduces temperature fluctuations in the system.

Abstract: ABSTRACT OF THE DISCLOSURE           A method for batch pulp digestion with hydroxide-bearing cooking liquors in combination with continuous alkaline oxygen delignification is described. The brown stock washing plant and the connected oxygen stage are disengaged from oxygen-consuming substance by removing black liquor from a pre-cook with a surplus of hydroxide-consuming chips; besides black liquor in the brown stock washing plant is displaced with oxy spent liquor (bleaching spent liquor from the oxygen deligni-fication stage) and/or alkalization spent liquor (bleaching spent liquor worth recovering because of its sodium content) and a mixture if said liquors is used for charging liquor to digesters or to the digestion plant liquor system. The circulating cooking liquor content of hydroxide for lignin release is continuously regulated by means of white liquor dosage which is controlled according to the dilution which is caused by the supply of bleaching spent liquors whose hydroxide content reflects variations in digesting conditions and thereby caused Kappa number fluctuations.

Abstract: ABSTRACT OF THE DISCLOSURE A novel method is provided for making carpet underlay.  The method includes the steps of: providing a sheet of elawtomeric material which is adapted to define the carpet underlay; supporting the sheet on supporting means comprised of wire-like mesh material having openings with elongated flat shrip inserted therein; and subjecting the sheet to a controlled heated environment while supporting the sheet on the supporting means; the heated environment causing the sheet to soften and droop around the mesh material with the extent of drooping being limited by the flat strip means and the strip further preventing the sheet from passing through the openings in the mesh material; the heated environment also causing simultaneous expansion and curing of the sheet.  In one variant, the supporting means  comprises wire-like mesh material having a plurality of undulating members with each adjacent pair of undulating members being held together by a common tie  mem-ber with the elongated flat strip means being supported by each undulating member and wherein the sheet, which has been softened and droops, thereby droops around the undulating and tie members.  In another variant, the means is in the form of an endless conveyor means, and the heating of the sheet mesh material thereby forms a plurality of U-shaped channels in the upper sur-face of the sheet.  By these steps, the heated environment also causes simul-taneous expansion and curing of the sheet.  In this way, the carpet underlay is defined having a plurality of cooperating coplanar portions defined by the strip means separated by channels defined by the undulating and tie members.
